Glass ceramic stove and subassemblies therefor
First Claim
1. A cooking stove assembly having a glass-ceramic cooking plate in combination with at least one burner assembly, each such burner assembly having a housing and a perforated burner plate in combination therewith, said burner plate and said housing together defining a burner chamber, said burner plate being disposed generally across an upper portion of said housing, said burner plate being generally spatially located in spaced parallel relationship to the underside of said cooking plate, said housing and said burner plate being maintained in fixed relationship to said cooking plate by a peripherally extending generally upstanding ring member secured on its lower edge portions to said housing and/or to said burner plate, and secured on its upper edge portions to said underside by elastic sealing means, said burner plate, said cooking plate, said ring member, and said sealing means together defining a heating chamber, each such burner assembly further having located in said heating chamber (A) a temperature sensor for temperature limitation, serving to detect when said cooking plate is exposed to predetermined excessive temperatures, (B) an ignition means for igniting gas, (C) an ignition safety means for detecting if gas ignition does not occur after operation of said ignition means, and (D) an energy regulating sensor adapted to sense temperatures within preselected temperature ranges.
